Use the right specialty shipping envelope to mail flat items that require some added protection, such as additional rigidity for bendable documents or lined envelopes for confidential papers.
Also known as expansion mailers, these envelopes expand to hold bulky items such as books, magazines, or a large amount of documents.
Keep package contents concealed when shipping confidential, sensitive, or classified documents using these mailers. They feature a silver lining that reduces the ability to see through the envelope.
Keep items such as photographs, x-rays, and flat items unbent using a mailer made of strong, rigid chipboard.
